There’s no doubt that Diane Kruger was exquisite last night in her haute couture ball gownat the Closing Ceremony of the 2012 Cannes Film Festival, but even she couldn’t stay in something so voluminous all night.

The 35-year-old actress slipped into a dress that much more moveable when she attended the Winner’s Dinner with her boyfriend Joshua Jackson.

Diane arrived to the fête in a two-toned, long-sleeve silk gown from the Fall 2012 collection by Jenny Packham. The top portion of the dress featured white stripes made up of white polka dots; black took over at the jewel-embellished cuffs and the drop-waist skirt, which included the same stripe pattern but with black dot embellishing.

Because of the loose fit, a black belt cinched high on the waist for a little definition.

This was a beautiful choice for Diane, but then again, I’m convinced she could wear anything and look great.

She left her hair up in a ponytail and finished off with a Edie Parker gold confetti and white pearlescent striped “Jean” clutch.

Angelina Jolie may have skipped the Cannes Film Festival this year and put the kibosh on my Wish List gowns for her, but at least Diane still gave me a great red carpet moment with a dress from Packham’s collection.
